Hi I have difficulty installing the firedrake on Mac using homebrew. Hope someone could help. Sorry that I don't find make.log

This is the error message of my configure log:

Downloaded ptscotch could not be used. Please check install in /Users/chengbinzhu/firedrake/src/petsc/default

You get lots of warnings like:

ld: warning: object file (/Users/chengbinzhu/firedrake/src/petsc/default/lib/libscotch.a(vmesh.o)) was built for newer macOS version (11.0) than being linked (10.15)

I think this is an issue we've yet to have solution for. According to

firedrake/scripts/firedrake-install

Line 1095 in 3b0b09e

# Set MACOSX_DEPLOYMENT_TARGET to the current macos version

, you'll get around the issue for now by changing MACOSX_DEPLOYMENT_TARGET to your current macos version in line 1099 of firedrake-install.
